On Christmas morning, a 14-year-old boy falls from the top of a school building. The police announce the boy's death as a suicide and his parents are in agreement with the report. Rumors though quickly spread about the boy's death. An anonymous note is then received by the police. The note claims that the sender was a witness during the boy's death. The note also claims the boy was killed by three troubled students at the school.

To protect the students, the police hides the anonymous note, but a reporter gets the note. The situation then becomes uncontrollable. Another student dies in an accident. Students are hurt by the situation and decide to hold a trial by themselves to uncover the truth.
